Sera wrote about delicately flavoured liquid (9)

I believe the answer is:

rosewater

I'm a little stuck... Click here to teach me more about this clue!

'delicately flavoured liquid' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'sera wrote about' is the wordplay.
'about' indicates an anagram.
'sera'+'wrote'='serawrote'
'serawrote' anagrammed gives 'ROSEWATER'.

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
